I know this is a totally unrelated point but the software and network side of thing really leave a lot of room to be desired.
Glad your wait for the Nova has been worth it, David. I got to listen to my sister's Nova this last weekend - like you, hers had been on back order for over a year. She's equally delighted with it, though barely scratching the surface of its potential with her source material - sounds great with Tidal, happily. Suspect I'll be sorting a NAS and curating a library of high quality source files for her shortly...
I think a distinction needs to be drawn between the iOS and Android control software - most iOS users seem to get on fine with it, with the important caveat (made emphatically by Huge on this forum) that the implementation of network discovery/sockets protocols leaves a great deal to be desired. Like many, I have used Sonos products for donkeys years, and in the last year or two, have never had a problem - currently have 8 of them, and multi-rooming is consistently a hassle free process - bearing in mind I'm also streaming full fat files from Tidal on my Sonos kit. The key difference is that Sonos is a $1b company whilst Naim's turnover is measured in tens of millions of £'s. Interestingly, the Naim website states that:
"Naim Audio are starting on an exciting phase of development for the future of our mobile apps, so we're looking for an enthusiastic and skilled Software Engineer who has particular strengths in Apple technologies to help us realise our vision."
I'm glad I'm not an Android user, as these unfortunate souls seem to be the ones struggling with app functionality - again primarily around network discovery, but also app stability.
Like you, I'm keen to see Naim prosper and sustain vigorous ongoing development. In this context, I'm delighted that Naim have invested time to revisit the firmware for legacy streamers such as my Superuniti - I'm currently listening to this, and greatly enjoying its revitalised SQ post firmware update 4.6. It deserves credit for that.
